This course was originally written to teach researchers to analyse data using Stata, which was the analysis program of choice in the Centre for Epidemiology for many years. We are now encouraging the use of R within the Centre in parallel with Stata, and David Selby has kindly rewritten all of the Stata practicals so that they can be run in R. This is still a work in progress: not all Stata concepts map cleanly to R versions, so both the Stata and R versions will need some editing to produce something that is both meaningful and identical in both cases.
